HARRY sQ WHEATONX or DALLAS, IOWA.

SANITARY 'rnnnrrroivn MOUTHPIECE.

Application filed May 26,

To all whom it mayconccm:

- Be it known that I, HARRY S. -IIEATON, a citizen of'the United States,residing at Dallas, in the county of Marion and State of Iowa, haveinvented certain new and useful Improvements in a Sanitary TelephoneMouthpiece, of which the following is a specification.

This invention relates to a sanitary telephone mouth-piece and has forits principal object to provide means combined with a mouth-piece forcontaining a disinfectant fluid.

Another object of the invention is to provide a device of this naturewhich is automatically opened and closed by means of the receiver hookusually found upon telephones now commonly in use.

A still further object of the invention 1s to generally improve uponsanitary mouthpieces of this character by providing a device which willbe of extremely simple, durable and inexpensive construction, one whichis eiiicient and reliable in operation, and well adapted to the purposefor which it is designed. With these and numerous other objects in view,the invention resides in certain novel features of construction, and thecombination and arrangement of parts as will be hereinafter fullydescribed and claimed.

In the drawing:

Figure 1 is a front elevational view of the device showing same attachedto a telephone transmitter.

Figure 2 is a side elevational view thereof.

igure 3 is a vertical section taken there through.

Figure 4 is a vertical section taken therethrough at right angles to theview shown in Figure 3', and

Figure 5 is a rear elevational view of a transmitter of conventionalconstruction showing my device attached thereto.

Referring to the drawing in detail it Wlll be seen that 1 designates thetelephone generally which is provided with the usual transmitter 2 whichmay be of any conventional construction and as usual is provided with aprojection in the form of a flange 3 for receiving a mouthpiece. Thisconventional mouthpiece, however, is not used in the present instance.My device consists of a casing formed by the annular rim 1 to which issuitably attached a front plate and a rear plate 6. A flange 7 ofcircular con- Specification of Letters Patent.

struction is attached to the front plate 5 so as to extend inwardly andto be spaced from the rim l. Another rim of circular construction 8 isattached to the plate 6 and is slightly spaced from the flange 7. Theplate 5 is provided with apertures 9 and an apertured disk 10 is mountedon the shaft 11 and keyed thereto and this shaft 11 is journaled in theplates 5 and 6 so that the disk 10 may be rotated whereby its aperturesmay register with the apertures 9. A similar disk 12 is keyed to theshaft 11 adjacent the-rear plate 6 and is provided with aperturesadapted to register with apertures 13 in this rear plate 6. Asemi-circular slot 14 is provided in the front plate 5 and a pin 15suit-ably carried on the plate 10 projects therethrough. A rod 16 ispivotally mounted on the pin 15 and is connected with a clamp 17suitably mounted on the receiver hook 18. As shown clearly in Figure 1when the receiver is removed from the hook 18 the rod 16 will be pushedupwardly so as to slightly move the pin 15 causing the apertures in theplates 10 and 12 to register with the apertures in the plates 5 and 6. Awasher 19 is suitably attached to the outer side of the plate 6 by meansof glue and receives the projection 3 of the transmitter 2. In order tohold the casing to the transmitter a plurality of lugs 20 are attachedto the rear plate 6 for hingedly receiving the links 21 which are curvedso as to conform with the rear 'ieriphery of the transmitter 2. A splitring .22 is received by the ends 23 of the links 21 and a nut and bolt2% are associated with the ends of this ring 22 so as to hold the link21 in firm engagement with the transmitter 2 thereby holding the casingtightly thereon.

An aperature is provided in the rim 4 for X1 receiving a closure plug25. This plug 25 is ada ited to be removed in order that a disinfectantliquid may be poured into the easing. This liquid will contact with theflange 7 and flow to the bottom of the casing. Should the casing at anytime be turned upside down this flange 7 would cause the liquid to flowto the other end of the receptacle. Any liquid which might flow over theedge of this flange 7 would engage with the flange 8 and be transmittedto the bottom of the receptacle as will be readily understood.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the device willbe readily understood without a more extended explanation. As numerouschanges in form, proportion, and in the I claim as new is 1. Amouth-piece of the class described comprising a casing having a frontand rear wall provided with perforations, a pair of plates disposedwithin the casing adjacent the wallsthereof and provided with aperturesfor registering with the apertures of the walls and means for rotatingthe plates so as to place their apertures in registry or non-registrywith the apertures of the walls in the manner and for the purposespecified.

2.,A mouth-piece. of the class described comprising a casing including afront and a rear wall, a flange extending from theinner side of thefront wall and another flange ex tending from the inner side of the rearwall so as to be spaced from the first mentioned flange, said wallsprovided with apertures, and a pair of'rotatable plates mounted in thecasing and provided with apertures adapted to be placed in registry withthe apertures of the walls in the manner and for the purpose specified.

3. A mouth-piece of the class described comprising a casing including afront and a rear wall, a flange extending from the inner side of thefront wall and another flange 'ing the casing to a transmitter of atelephone.

In testimony whereof I aflix my signature in presence oftwo witnesses.
